Well it's not supposed to look undead so much as just evil.

edit: But I did fix the eyes and lips a bit.

maybe u could add texture and stuff to make it more interesting + undead. one of jocher's pieces but a good example: http://i39.photobucket.com/albums/e199/sharprm/zombie3.png

Yes sharprm. My face.

The purple on the lips seems a little odd but ither than that nice job.

The previe is quite trippy as well because it looks like a front view but when you full view it its almost an isometric view. 

i like his right eye. did u use a ref?
